GARBAG E-BU RN ER AND WATER-HEATER.

$PECIFIGATION forming part of Letters Patent No. 718,490, dated Januar 13, 1903.

Application filed March 25, 1902. Serial No. 99,887. (No model.)

To all whom, it may concern.-

Be it known that 1, JAMES MANN, a citizen of the United States, residing at Dowagiac, in the county of Cass and State of Michigan, have invented certain new and useful Improvements in Garbage-Burners and ater-Heaters, of which the following is a specification.

My invention relates to a garbage-burner, in its preferred form to a combined garbageburner and water-heater, the objectof which invention is to provide a simple and efficient device of this character and one capable of utilizing the heat for the purpose of heating water.

The points of advantage and utility in the construction and'arrangement of my garbageburner will be apparent from the description hereinafter given.

In the drawings, Figure 1 is a plan view of my garbage-burner; Fig. 2, a side elevation thereof; Fig. 3, a sectional plan on the line A B of Fig. 4; Fig. 4, a sectional elevation on the line C D of Fig. 3, and Figs. 5 and 6 modifications of the garbage-grate and associated parts. V

As wood, hard coal, soft coal, or gas may be the fuel employed for the drying and initial burning of the garbage, provision is made in my burner, about to be described, for the use of either one of these kinds of fuel, comparatively slight changes being made to adapt the burner to the particular fuel employed, such changes not necessitating a departure from the general principle of my invention.

Referring first to the hard-coal-burning apparatus, my burner, which is preferably a cylindrical shell, comprises the lower section or shell 1 and the upper section orrcasing 2, the former containing a fire-grate 3, forming below an ash-pit 4. This lower section sup,- ports in a suitable manner the upper section 2, which has double walls 5and 6, forming between them a water space or jacket 7. In order to prevent clogging or' packing of the garbage in a solid mass, which would choke or stop the draft, and also toincrease the heating-surface of the water jacket, the inner wall 6 is made corrugated or fluted, as seen in Fig. 3. The upper section or shell 2 is closed at its top by a plate or cover 8, supported thereon and provided with a depending magazine 9, adapted to feed coalhard Within the upper section or shell 2 at the lower end of the garbage-chamber and above the fire-chamber is arranged a garbage-support 15, which may be said to separate the fire-chamber from the garbage-chamber and which has a central opening to'receive the magazine,projecting a slight distance through it and into the fire-chamber, as seen in Fig. 4.. The garbage-support is inclined and is slightly less in diameter than the inside measurement of the shell 6, whereby an annular space is left for a purpose hereinafter explained.

The garbage-support, which in the present instance is shown as substantially truncated conical, is cast hollow to form the water-space 16, through which water way circulate, and is provided with a plurality of transverse fireopenings 17. supported in suitable manner within the shell or casing 2 and may also be suitably connected as to its water-space with the water space or jacket 7, and in the present instance I have utilized such water connection as such support, whereby such water connection or pipe has a twofold function, as shown. Short pipes 18 screw through the inner walls 6 of the shell or section 2 and enter screw-threaded holes, which communicate with the waterspace of the garbage-support. As illustrated in Fig. 3, a hot-water pipe 19 leads from substantially the highest and hottest point of the garbage-support above the plane of the pipes 18 up through the garbage-chamber, and, as illustrated in Fig. 4:, the water space or jacket 7 is provided with a supply or intake pipe 20. The direction of circulation of the water is downwardly through the water-jacket at the coolest point through the short pipes 18 and through the garbage-support, and finally up- The garbage-support may be wardly through the hot-water pipe 19, leading from the hottest point to a suitable reservoir or place of use.

As herein shown, the garbage-support is substantially cylindrical at its lower portion, while its upper portion slopes gradually inwardly and upwardly from the upper corner or margin of such cylindrical portion. This support, which is an integral structure or casting, as illustrated, with an interior waterspace and transverse fire openings, is of slightly less diameter than the inner shell or casing, whereby an annular space is left or formed between such casing and such cylindrical portion of the garbage-support. The short transversely-armnged pipes, as hereinbefore described, pass through such inner casing, across the annular space, and into the sides or cylindrical portion of the garbagesupport, thereby accomplishing the twofold function hereinbefore mentioned.

From the foregoing explanation the operation of my burner is obvious. The heat of the coal supplied from the magazine will keep drying and burning, the garbage coming in contact with the garbagesupport and the products of combustion passing from the garbage-chamber through the fine 21 at the top. Thus the garbage will be dried and will slide down the inclined support and, falling through the annular opening at the edge of the support, will be effectually consumed and disposed of in the fire-chamber below, and at the same time the heat of combustion will be utilized in heating the water in the garbage-support and in the water-jacket. Of course the top of the magazine may be provided with any suitable lid, such as the lid 22.

The corrugating of the inner wall of the upper shell serves the twofold function of increasing the heating-surface and of preventing the packing of the garbage in a solid impenetrable mass at the sides, so that the draft through the garbage-chamber will never be fully obstructed.

As hereinbefore suggested, my garbageburner may be adapted for the burning of soft coal, as well as of gas, such adaptation being possible by the making of very simple changes in the construction already described.

Referring to Fig. 5, the garbage-support here shown is adapted for soft coal. Consequently the coal-magazine useful for hard coal is dispensed with and the coal is introduced through the fire-door 2". In order to supply the proper amount of air in addition to that supplied through the ordinary damper 2 in the fire-door, I provide a down draft or current of air, whereby complete combustion of the coal is possible. To this end an air-pipe 23 is screwed into the garbage-support, which has a smaller central opening than that illustrated in Fig. 4. This pipe is secured to a disk or plate 2-:t at its upper end, which plate takes the place of the lid 22. Under this arrangement air is drawn downwardly through the air-pipe and supplied to the fire-chamber.

If desired, the upper end of the air-pipe may be provided with any form of damper or regulator 25, which may be suitably pivoted and permit a greater or less opening at the upper end of such pipe.

Referring to Fig. 6, the garbage-support here shown is adapted for the burning of gas as the fuel, and in this instance a pipe 26, which is a water-pipe, screws into the garbage-support in such manner as to communicate with its water-space, such pipe corresponding to and taking the place of the hotwater pipe 19. (Illustrated in Fig. This hot-water pipe may be suitably supported at its upper end in a manner similar to pipe 23 by means of a disk 27.

If desired, several lugs 28 may be provided on the inner wall 6 to steady the garbage-support, especially in shipping from the shop or factory, when wooden blocks would be driven down between such support and the wall 6.
